Geri Halliwell has reportedly snipped the string on her history of yo-yo dieting and reportedly "feels better than ever," staying in shape with plenty of yoga and "healthy eating." Meanwhile, Emma Bunton works out three times a week, usually running on a treadmill.

*US Weekly'*s diet and exercise report on the ever-sporty Melanie Chisholm: she feels "more feminine than ever before." So I'm not sure what that means. But as of last year, she was training hard to compete in a triathlon, doing total-body circuits that included step jumps and declined bench press-ups--and, like Victoria, plenty of coconut water. After having baby Harper, she also reportedly ran six days a week and had a "strenuous exercise regime" under star trainer Tracy Anderson.

Mel B does one- to two-hour treadmill workouts and likes to go for hikes--complementing her workouts with sessions of 600 sit-ups. She told People: "I've always been obsessed with doing abs. I change positions every 10 reps. I like how quickly--if you stick to it--you can see results."
